Join Me is a ‘cult’ or ‘craze’ (or ‘fad’?). But looks like something typically classed as ‘British’ as it is kinda kooky or eccentric, but very nice and pleasant at the same time.

“One afternoon when Danny Wallace was very bored he decided place an advert in a paper which read simply ‘join me’. “

I won’t be joining however, preferring my random acts of kindness to be less planned and controlled, and more spontaneous and whimsical.
